SPECIFICATION forming part of Letters Patent No. 367,977, dated August 9, 1887.

/ Application filed March l), 1,887. Serial No. 233,033. (No model.)

To all whom t may concern:

Be it knownthat I, CHARLES D. HAZEN, a citizen of the United States,residingat Martinsburg, in the county of Lewis and State of New York, have invented certain new and useful Improvements in Devices for Bending Vood;

and I do declare the following to be a full,clear,

`wood, and the apparatus herein described is moreespecially adapted for forming plowhandles. l n A The novelty of the invention consists in the pecular combinations, and the construction, arrangement, and adaptation of parts, all as r more fully hereinafter described, and then l sented by dotted lines.

. slot, a.

specifically defined in the claims.

The invention is clearly illustrated in the accompanying drawings, in which- Figure l is a perspective view of my improved device, representing a plow-handle bent therein. Fig. 2 is a top plan of the saine with parts removed and others repre- Fig. 8 is a side elevation, partly in section. f Figs. 4, 5, and 6 are details, which will be fully hereinafter referredto. s

Referring to the details of the drawings, A

end with the bi fnrcated block a, either formed integral with or rigidly secured to lsaid bedplank. Near its longitudinal center this bedplank is provided with a transverse recess or groove, a', and in this recess is a longitudinal In line with this slot is the'depression B, which permits the operator to readily plank intermediate of these depressions arethe guide-strips B, so placed that the space between them willbe inline with the said depressions. Between the block aY and the recess a the bed-plank is provided with a plurality of holes, C C2, preferably four in number, the object of which will be hereinafter stated. Between said block'and recess said bed-plank is also provided,upon opposite sides of a line drawn through its longitudinal center, with h oles C', prefcrably'two in number, and also with an inclined slot, o', theobject of which will be hereinafter set forth.v Within a recess, D, at a point just beyond the transverse groove a', I pivot the bars D', the free ends of which are slotted, as shown at d.

E E are bars or strips placed across the recess a in such a manner as to leave a space, e, between them and a space beneath them, between said bars and the lower wall of the recess a.

F is a removable block of substantially the form shown, and provided with pinsf, which pass entirely through the same and project upon oppositei sides thereof, which pins are designed to engage either the holes G or C', 'as the case may be, the position of said block being changed as it is desired to form either a right or left hand handle; rlhis block is so formed that both sides are used for the shaping of either right or left hand handlesthat is to say, when in position shown in full lines it shapes one forni of handle, and when reversed, as shown in dotted lines, it shapes the other form of handle. This block is provided at one end with bifurcationsf, designed to engage a projection of the block a, as shown in Fig. 2. G Gare removable pins designed to engage the holes C2 at times during the processy vof bending. represents the bed-plank, provided near one His a pin or post provided with a shank V4somewhat smaller than the slot c' and adapted to 4engage therewith, said shank being made smaller than the slot, so as to allow the post to be adjusted therein when desired.

I is alooking pin or key,made wedge-shaped, and preferably with offsets or shoulders t' to engage the links D' and prevent endwise displacement of said locking-pin, which pin or key is adapted to engage the slots ofthe bars D', for a purpose soon to be described.

J is a spring-strip or bender, provided at one end with a hook, j, which end is designed to fit into the space e between the strips E. When the wedge K is inserted into the groove a beneath the strips E, it engages said hooked end and firmly locks the same in place. The

IOO

opposite end of this bender is formed with a hook, L, with which engages the clevis M, pivoted to the grapple stay-brace or bender N, which is provided with a shoulder, N, and a hooked end, 11, and a shoulder, a. The shoulder N of thc stay-brace serves to form a ses cure bearing ior the end of the bending-lever. O is the bendinglever, curved as shown, to correspond with the curvatui-e of the grapple stay-brace, and provided with a shoulder, o, which in practice is designed to engage the shoulder N and forni a purchase therefor.

The operation oi' the deviceis as follows It being our purpose to irst form a mold-board or rightliand handle, the removable block F is placed in the position indicated in Fig. l of the drawings. The spring bending-strip J is then placed in position, with the hook j fitted into thespaee e. The heel of thehandle to be bent is then placed in position within the recess in the block a, and the handle is then pressed against the block F until the fulerumpost I-I can be set in the hole C', which is provided at a point necessary to secure the desired bend or curve to the handle. By thus regulating the position of the post any desired curve may be secured. The handle is then pressed back against the post until the pin f can be set in the hole C nearest to the slot c. 'Ihe key or wedge K is then pressed within the groove a a sufficient distance to cause the heelV of the handle to bear well against the block a. The clevis M of the bender N is then applied to the plate-hook L, and the operating-lever O is applied in such a manner as to cause the shoulder o of the lever to bear against the corresponding shoulder n of the stay-brace. The lever is then forced downward until vthe dcsired bend is obtained, when the locking-pin I is forced into place within the slots of the bars D. The lever O may then be removed, and the bent handle, thus locked in position, is in readiness for kih'rdrying. In bendinga left-hand handle the block F is placed upon the opposite side of the bedplank, its ends are reversed, and the block is turned over, the pins f, which project from opposite sides of the block, fitting in the holes C. The block when thus placed will occupy the position indicated by dotted lines in the drawings. The process just described for bendinga ri ght-hand handle is then repeated, excepting that the post H is omitted and the handle is pressed against the block F until both of the stay-pins can be inserted. It will be observed that in bending a left-hand handle the post II is dispensed with and the pins G- are inserted in the holes C2 and serve to hold the handle in position against the block F.

Having thus fully described my inventon and set forth its merits, what I claim to be new, and desire to secure by Letters Patent, is-

1. The combination, with the bed-plank provided with holes C CQ of the removable and reversible block F, provided with pins f, projecting from opposite sides of the block and adapted to the holes C C', substantially as and for the purpose described.

2. The combination, with the bed-plank provided with block a, havingA bifurcated end, and with holes C G and inclined slot c', of the block F, pins projecting from cach side of said block F, and post H, substantially as and for the purpose described.

3. rIhe combination, with the bed-plank having block a., holes C C', the inclined slot c', and holes C, of the removable reversible block F, provided with pins f, as shown, the relnovable post ll, having a shank engaging said slot, and the removable pin G, substantially as and for the purpose described.

4. The combination, with the bed-plank provided with block aand holes C, G, and C2, of the reversible removable block F, provided with pins f, and the removable pins G, substantially as and for the purpose described.

5. In a device for the purpose described, a spring bending strip provided at opposite ends with hooks, as j L, combined with a clevis engaging said hook L, and a stay-brace carrying said clevis, substantially as and for the purpose described.

6. rIhe combination, with the bending-strip provided with hook L, oi' the grapple staybrace, and clevis M, pivoted to said stay-brace, 95 and a removable lever engaging said staybrace, substantially as and i'or the purpose described.

7. The combination, with the bed-plank recessed transversely, as at D, as described, o( IO@ the bars D', pivoted to said recess, and slotted, as described, the bending-strip J, having hook L, the grapple stay-brace N, provided with hooked end ny and clevis M, and the key I, substantially as and for the purpose described.

8. The combination, with the bending-strip J, provided with hook L, ofthe grapple staybrace N, formed with shoulders N and u', the clevis M, pivoted to said stay-brace, and the lever O, having curved end and provided with i ro shoulder 0, substantially as and for the purpose described.

9. The combination, with the bed-plank, of the bars D', pivoted to said bed-plank and slotted, as described, the bending strip J, ii 5 grapple stay-brace N, the clevis carried by said stay-brace and engaging said strip, and the removable key I, all substantially as and for the purpose described.
